| Abstract: | Photoassisted selective catalytic reduction (photo-SCR) of NO with NH3 in the presence of O2 takes place at room temperature over TiO2 photocatalyst. From the results of photo-SCR reaction over various TiO2, we found that JRC-TIO-11 exhibited the best activity. The reaction activity correlated to the amount of acid sites of TiO2, but did not depend on the specific surface area and crystal diameter. The mixture of rutile and anatase shows higher activity than any of the corresponding TiO2 single phase catalyst. |
